Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved structure of a racket shock absorber block,
It includes upper and lower sandwiches, and upper and lower sandwiches are provided with several through-holes, each through-hole is provided with a rivet bar, and the upper and lower sandwiches are sandwiched. In addition, the upper and lower ends of the gut of the racket are sandwiched between the rackets, and the racket is fastened and fastened with a fastening rod, so that the assembly is convenient, and the object of improving the rigidity and the shock absorbing effect is achieved.

[0002]

2. Description of the Related Art The structure of a conventional racket is shown in FIG. 11, which is mainly composed of a racket frame 50 through which tightly distributed guts 51 are passed. It is formed. However, when the ball is hit hard with the racket, the gut has elasticity, so that an extremely large repulsive force is generated on the gut 51, and the repulsive force gives the racket an extremely large vibrational force. 50, the hand is transmitted to the player's hand through the grip, so that when the ball is hit, hand vibration is always generated due to excessive vibration force, and the phenomenon that the grip is unstable and the racket falls off occurs. In order to improve the above-mentioned drawbacks, rackets are often provided with a shock absorbing device at present.
One method is to install a shock-absorbing block. The shock-absorbing block is mounted on the gut, and the effect of the shock absorbing is achieved by reducing the vibration force of the gut.

FIG. 10 shows the structure of an existing shock absorber block. The shock absorber block has a single body 60 which looks flat and is provided with a gut 51 at both end surfaces thereof. When the assembling is performed, the main body 60 is connected to the adjacent gut 5.
1 and each gut 51 is inserted into the fitting grooves 61 at both ends of the main body 60.
The main body 60 is fixed on the gut 51. However, such a conventional shock absorber block has the following several drawbacks during implementation due to its poor structural design.

[0004]

[Problems to be solved by the invention]

1. The fitting structure is not firm and has poor stability. It is provided with fitting grooves 61 at both ends of the main body 60, and the gut 51 is fitted into the fitting groove 61 and fixed at a fixed position. The fitting groove 61 has a fixed width, and the gut 51 is formed only by the fitting method. If it does not fit into the inside and has no other fastening structure, the rigidity is low, and if it is subjected to a large vibration, the main body 60 easily falls off, which is inconvenient for use.

[0005] 2. The vibration absorption effect of the single shock absorber is not very good. It is only a single body 60 with mating grooves 61 at both ends, without any resonant design or auxiliary design to absorb vibrations such as weights, and the single structure fits over several guts. I can not attach it,
The main body can fit only two guts at most, and therefore moves with the vibration of the gut, and immediately transmits the vibration from the gut as it passes through the main body 60,
Since the vibration absorbed by the vibration is very limited, the vibration absorbing effect is not so good.

[0006] 3. The unitary structure cannot cross many gut lines or cross points, and has low applicability. The fitting grooves 61 at both ends of the single main body 60 are
Since only one can be fitted, it must be made into a small feature (its width is slightly larger than the spacing between two guts). Therefore, when mounting a large-area shock absorber on one racket, the conventional one must use many shock absorbers, and these shock absorbers cannot be arranged in a straight line. , Cannot be installed at crossing points, and therefore, those conventional ones cannot completely meet demand and cannot be installed at necessary places.

In view of the drawbacks such as insufficient rigidity due to insufficient design of the conventional device, poor stability, insufficient vibration absorbing effect and low applicability, the inventor of the present invention has made an active effort. After extensive research and many tests and improvements, we were able to finally develop a practically useful invention.

The main object of the present invention is to provide a racket shock absorber block which is easy to assemble, has high rigidity, good vibration absorption effect and wide applicability, including an upper and lower sandwich. The upper and lower sandwiches are provided with several through-holes, and each through-hole is provided with a rivet bar.
